In a smoke warning system ambient conditions are included in the evaluation of the smoke warning transmitter statuses, or the internal signal evaluation in the smoke warning transmitter is influenced. In this procedure the alarm threshold of the system is raised under certain ambient conditions so that the smoke warning transmitter per se is set so as to be less sensitive.
